Acharya Prashant explains the distinction between the individual soul, the Lord, and the ultimate Truth. He clarifies that the individual soul, identifying itself with the physical body and objects, perceives the world as a creation and thus invents the concept of a creator or Lord. This Lord is described as a product of ignorance and illusion, created by the individual soul to satisfy its need for a protector or judge. While the Lord is associated with qualities and duality, the ultimate Truth or Brahman is non-dual, attribute-less, and beyond all prayers or descriptions. The speaker emphasizes that those living in body-consciousness speak of the Lord, while those established in the Self speak of Brahman.
